TO ALL WHOM IT MAY CONCERN: 7

Be it known that I, Issac D. JOHNSON, M. D., of Kennett Square, in thecounty of Chester, and State of Pennsylvania, have invented a new anduse'ful Improvement in Carriages, called a Check-Brace; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable those skilled in the art to make and use thesame, reference being had to the annexed drawings, formingpart of thisspecification, in which- Figure 1 represents a. side view of the underparts of a carriage, showing the position the braces B B are in when thesprings F and G are elevated.'

Figure 2 represents a similar view, and the position of the braces B B,when the springs F and G are depressed.

A represents a stifl brace, constructed of iron or other suitablematerial, and attached to the upper half of i the spring or spring-barE, the lewer end being made to stand down half the width of the spring.

0 represents a semicircular'br'ace, also made of iron or other suitablematerial, and secured to the perch-- pole D. Attached to this bracefandpassing over it, is a thin plate of iron or steel, Bflvhich connectswith the lower end of A by a loop-joint, the three pieces, A, B,' and'(l, forming the front brace. Now, when the spring F is elevated ordepressed, a'ccri'esponding motion is given to the brace A, and theflexible plate B passing over 0, the tension is so adjusted as to admitof no jostling of thespring forward.

Attached-to the back sp'ring'G is another brace, B, constructed inprecisely the same manner as the onein front, and the two, acting inharmony with each other, permit the springs F and G to play up and downwith the greatest freedom, while they preclude the possibility ofany-motion in a. horizontal direction. I'Icnce,'the breaking ofspringsand bolts, and the liability to accidents consequent thereof, isin a great measure prevented.

What I claimas my invention, and desire to seizure by Letters Patent,is-

The combination of the two braces B B, their attachment to the upperhalf of the springs or spring-bars E E, the braces A and C; and theflexible plate 13, all constructed, arranged, and employedin themanner-and for-the purpose herein. sho\ vn and described.
